Fittings for Threaded Pipe systems
Definition and Details of Threaded Fittings ASME B16.11
Threaded joints, perhaps one of the earliest methods for connecting piping systems, find their primary application in small pipe diameters, often referred to as small bore piping, typically encompassing pipes with a nominal diameter of NPS 2 or smaller.
The ASME B1.20.1 standard serves as the definitive source for dimensional specifications pertaining to taper pipe threads. This comprehensive document provides essential details, including the number of threads per inch, pitch diameter, and normal engagement lengths for all pipe diameters.
Threaded piping is most commonly employed in cost-effective, noncritical scenarios, including domestic water supply, fire protection systems, and industrial cooling water networks.
Threaded fittings are typically crafted from materials such as cast gray or malleable iron, cast brass or bronze, as well as forged alloys and carbon steel. These fittings are accessible in three distinct pressure ratings: Class 2000, 3000, and 6000.
NPT Thread
Every fitting featured on this page is equipped with NPT threads conforming to ASME B1.20.1 standards. NPT, short for the American National Pipe Thread Tapered, stands as the most renowned and extensively utilized connection method, serving as both the mechanical joint and hydraulic seal. NPT threads feature a tapered male and female thread design, creating a seal when paired with Teflon® tape or jointing compound.
Advantages and Disadvantages of Threaded Fittings
Advantages
- Installation productivity is reasonably elevated, with only moderate demands for specialized installation skills.
- Leakage integrity is commendable in low-pressure, low-temperature installations that do not experience significant vibration.
Disadvantages
- Sudden temperature fluctuations can induce leaks by causing differential thermal expansion disparities between the pipe and fittings.
- Vibration has the potential to trigger fatigue failures in threaded pipe joints, primarily due to the heightened stress concentration at the sharp notches found at the thread base.
- In hazardous piping systems, it is advisable to steer clear of threaded connections whenever feasible. They exhibit notable susceptibility to fatigue damage, particularly in cases where exposed threads are susceptible to corrosion.
